Checks if the first character after any whitespace in a piece of JSON text is a colon.
JSONGETCOLON(p,l)
JSONGETCOLON reads up to and including the first non-whitespace character in the JSON text buffer to see if there is a colon (:) character. If there is, JSONGETCOLON returns the position of this character; otherwise a zero is returned indicating that it is not found.
Assuming buffer (pointed to by p) contains 2 blanks followed by :"Presley"}, Bytes = jsongetcolon(p,l); will return 3 (position of :).
None.
